“There were 20 deaths, most of them young children,” said the head of Niger’s fire service, Col. Bako Boubacar.
He said the origin of the fire in Niamey was unknown.

“The fire apparently started around the school gate. Without an emergency exit, many were trapped and students were forced to scale the wall to escape.
